Daniel Verkamp 983228e99f hypervisor: notify all Vcpu types on suspend 
Change the function name from pvclock_ctrl() to on_suspend() to make it
less confusing, and make the Vcpu figure out whether any work is
actually needed internally instead of making the caller check a
capability. This means that Vcpu::on_suspend() will always be called,
but most implementations will just do nothing (only KVM on x86 and WHPX
implement an on_suspend that actually takes action for now).

Hypervisor Support

Multiple hypervisor backends are supported. See Advanced Usage for overriding the default backend.

Hypervisors added to crosvm must meet the following requirements:

  • Hypervisor code must be buildable in crosvm upstream.
    • Within reason, crosvm maintainers will ensure the hypervisor's code continues to build.
  • Hypervisors are not required to be tested upstream.
    • We can't require testing upstream because some hypervisors require specialized hardware.
    • When not tested upstream, the hypervisor's maintainers are expected to test it downstream. If a change to crosvm breaks something downstream, then the hypervisor's maintainers are expected to supply the fix and can't expect a revert of the culprit change to be accepted upstream.

KVM

  • Platforms: Linux
  • Tested upstream: yes

KVM is crosvm's preferred hypervisor for Linux.

WHPX

HAXM

Android Specific

The hypervisors in this section are used as backends of the Android Virtualization Framework.
